I suppose emulating STM32s is all we can do at the moment. Impossible to buy one until sometime in 2023. On a more serious note: Great project!

I thought MCUs popular in both industry, college, and among hobbyists would be more readily available by now.

What is actually possible to get your hands on now? What about 32-bit ARM Arduinos and ESP32s?

We're using ESP32s in everything, originally because they're pretty great (what's not to love about lots of IO combined with wifi and bluetooth?) but also now because they're the only thing you can get.

How come STM32s are not available? I thought the chip supply issues were mostly related to smaller process nodes while these should be made on relatively older ones.

No there's an everything shortage in electronics. Fancy chips, old chips, power chips, capacitors, connectors, epoxy resin.

The short answer is that they are not building more fabs for non-leading edge processes, like those used by STM32.

There is an interesting video about this:
